To all whom it mag/concerm y Be it known that I, SOLON S. JACKMAN, of

anesville, in the county of Rock and State of Wisconsin, have inventedan Improved Mode of Binding Grain and similar productions, to be attached to a harvester', of which the following is a specification:

My invention consists in binding sheaves of grain by means of a band formed around the exterior from the straw or fibers of the same, the band not having been separately made, but being formed during the operation gether, and wound around the sheaf, forming a complete and strong band for the same.

To enable others skilled in the art to make and use my invention, I will proceed to describe the same, reference being had to the annexed drawings making a part of this specication, in which- Figure lis an end view, Fig. 2 a front view, Fig. 3 a vertical or top View, Fig. 4 detached portions, and Fig. 5 a sheaf in process of being bound.

The same letters and gures indicate the same parts in each figure.

The grain from the platform of the harvester is to be carried by means of a revolving apron, or otherwise, up the inclined plane D, as shown at Fig. l, and deposited in the recess P in the wheels or disks B and B.

When a quantity sufficient to form a sheaf has been deposited the projecting pin 8, Figs. 2 and 3, attached to the loose pulley or wheel j', coming in contact with a concave arm of k, carries it downward by turning the shaft 4 one-fourth part of a revolution. E is a clamp or tongs, one arm of which, m, is made to move outward and inward by means of the groove in the wheel f, in which it runs, being made eccentric in one-fourth part of the circle, as shown atFig. 4, having an inclosed joint,

l, `which is made aV bearing to support the tongs in their operation. The wheels f and h are attached to the shaft of the tongs, which is made to revolveby means of h, which is one-half the sizeof f. The driving wheels or pulleys 6 and 7 being equal, the tongs must revolve twice while the loose wheelA revolves once. They are to be so adjusted that the arm on of the tongs shall pass through the eccentric whileB and'B are moved one-quarter of a revolution, thus opening, as at Fig. 4, allowing one sheaf to pass out and another to take its place, when they immediately close upon it, as at Fig. 3. The band is formed by means of the twister C, which is a cylinder having a central longitudinal cavity, of diameter sufficient to contain the band, from which is arradial spiral slot, as shown in Fig. l. At the end of the twister one side is provided with a pointed projecting lip, O, and is rotated in the opposite directionv from the drivingwheel z' by means of crossing the belt or using `an intermediate pinion.

When the grain comes into the tongs, as before described, it also comes in contact with the twister, which disengages a few straws from one end of the sheaf, as is more plainly understood by reference to Fig. 5. These straws, inl being carried forward by the twister, come in contact with the standard X, and pass into the spiral slot, where one or more projecting pins compel them to twist around each other. The relative speed of E and O is such that the surface of the sheaf will move three inches, more or less, at each revolution of C, so that an additional portion of ber is added to the band at every, say, three inches, and the rotation of the sheaf pulls three inches of the band from the twister, which is thus firmly wound around the exterior ofthe sheaf, as in Fig. 5.v In the rotation of B the loose grain deposited in the upper recess P comes in contact with the stationary concave n, Fig. 1, which presses it into P, so that as the band is twisted toward B and nit is wound around against the side of B, and when the sheaf has made one revolution the second coil tends to press upon the first coil, especially at the place of commencement, thus preventing a tendency to untwist. When the band has extended one and one-half times around the sheaf the arm ofthe tongsmenters the --eccen tric, the tongs open,

`and thetwist-pin 8,*by turning Band B' onevester may be lcommunicated to the driving-v shaft 3 in any manner to suit the circumstances, provided that the speed is such as to Y Yaccomplishthe binding ofthe sheaves as nearly as :possible inthe time required by the harvester to cutthe same.

yThe twister C may beoperated by means of acrossedlbelt with a guide-pulley; or by cogwheels with an intermediate pinion, and the fast-wheel h and the loose wheel f by means of chain-belts of` square links, with projections to'prevent the possibility of slipping.

.The'band being lattached to the sheaf at short intervals, as described, is not liable to become untwisted, vbut simply-preventii1gthe strawsfrom untwisting after the last joining toethe'sheaf is all the fastening Ithat is necessary.; This -may be accomplished by so placingthe'twister c as to operate on the under surfacew-of zthe sheaf while the standard X, being made shorter, is so inclined that when the sheaf, after being bound, in passing downward, will be divided, aportion of .thestraw being carried to the left ofthe twister, thus leaving the end of the band in the opening between the two portions of the sheaf.

-I do not claim thel binding of sheaves by means of a band formed of straw, nor of a band formed from the-straw of the saine. I- `make no claim to the mode in which the sheaf -is broughtfintothe vrecess, or pocket for bindl'of the butts Yfrom Ythe gavel at intervals, and

twisting the same-aroundthe bundle to aY pointpast theb'eginning, and securing thefend in a cleft.

2. In a grainfbinder, the combinationof the rotating clamping-tongs with the rotating twister G, having its lateral spiral slot-for the purpose of forming a band' around and attached to grain-bundles, substantially as described.

3. Twister C, standard X,clamp or tongs E, grooved wheel or eccentric f,in combination, substantially as-and for the purposes hereinbefore setforth.
